Michael Sevakis 292e7cab73 Gigabeat S: PMIC SPI improvement and bugfixes. 
Nick some aspects from the as3525 ascodec driver to improve throughput in
the beast's SPI communications by switching tranfer descriptors to the
caller's stack and getting rid of thread synchronization.

Fix a bug that suddenly became obvious that could permanently stall the SPI
driver because all data could be shifted out before the interrupt could get
serviced. In that case, it needs a kick to restart it. Should probably put
the SPI interrupt priority above DVFS.

A tweak to the event registration interface to simplify it.

..
adc-gigabeat-s.c Merge functionality of wakeups and semaphores-- fewer APIs and object types. semaphore_wait takes a timeout now so codecs and plugins have to be made incompatible. Don't make semaphores for targets not using them. 2011-03-02 08:49:38 +00:00
adc-target.h
audio-gigabeat-s.c Gigabeat S: Turn off hardware effects (tone and 3d) when doing digital loopback for FM recording otherwise the signal and levels are poorly represented in monitoring (can't just do ADC->DAC for general FM and get voice too). Some tweaking to input setup to improve gain a tiny bit. A little bit quieter startup too. 2010-05-26 05:13:45 +00:00
backlight-gigabeat-s.c
backlight-target.h
button-gigabeat-s.c Gigabeat S: Do simple direct keypad scanning rather than triggering a separate scan interrupt and it all does the same thing but with 1 tick less latency. 2010-12-29 18:20:31 +00:00
button-target.h
dvfs_dptc_tables-target.h i.MX31: Add a debug menu to play around with DVFS/DPTC settings for fun, testing or benchmarking purposes. Can set the CPU frequency working point, whether DPTC voltage scaling is enabled and change the software-programmable load tracking weights. 2011-01-22 16:58:17 +00:00
fmradio-i2c-gigabeat-s.c FS#12370: Initial RDS support for Si4701/Si4703 tuner (beast and clip zip) 2011-12-17 20:24:19 +00:00
gpio-gigabeat-s.c Try to fix r31346 2011-12-17 20:34:27 +00:00
gpio-target.h FS#12370: Initial RDS support for Si4701/Si4703 tuner (beast and clip zip) 2011-12-17 20:24:19 +00:00
headphone-gigabeat-s.c Merge functionality of wakeups and semaphores-- fewer APIs and object types. semaphore_wait takes a timeout now so codecs and plugins have to be made incompatible. Don't make semaphores for targets not using them. 2011-03-02 08:49:38 +00:00
i2s-gigabeat-s.c Gigabeat S/i.MX31/wm8978: Clean up clocking information in the general wmcodec/pcm drivers and move it to the target's wmcodec/i2s files. 2011-10-17 15:37:14 +00:00
kernel-gigabeat-s.c i.MX31: Now that it matters because there's a debug screeen that allows changing things while running, some DVFS/DPTC stuff has to be done more carefully. Trim out some stuff and group functions better as well. 2011-01-23 20:21:35 +00:00
lcd-gigabeat-s.c Convert remaining memframe LCDs that can be convert to common code. 2011-12-16 23:40:39 +00:00
lcd-target.h Collect some of the memory frame LCD C code. 2011-12-15 23:07:11 +00:00
mc13783-gigabeat-s.c Gigabeat S: PMIC SPI improvement and bugfixes. 2011-12-18 10:41:43 +00:00
mc13783-target.h i.MX31/Gigabeat S minor cleaning: Make HW access more obvious in places I forgot to do earlier. Reduce the number of structs that need to be filled-out for some drivers just to simplify a little. Change some types. 2010-05-07 10:53:19 +00:00
pcm-gigabeat-s.c Commit to certain names for cache coherency APIs and discard the aliases. 2011-12-17 07:27:24 +00:00
power-gigabeat-s.c i.MX31: Now that it matters because there's a debug screeen that allows changing things while running, some DVFS/DPTC stuff has to be done more carefully. Trim out some stuff and group functions better as well. 2011-01-23 20:21:35 +00:00
power-gigabeat-s.h
powermgmt-gigabeat-s.c Gigabeat S: Maintain power thread at realtime priority at all times so it may always service the watchdog on time regardless of playback priority. 2011-10-30 14:32:42 +00:00
powermgmt-target.h Gigabeat S: Use longer battery filter; lag is not a problem with voltage for charging since it's I-controlled. Initialize local copy of last_inputs for the power routines in target init otherwise the battery filter is reinitialized too soon. 2010-05-19 23:39:59 +00:00
system-gigabeat-s.c i.MX31: Now that it matters because there's a debug screeen that allows changing things while running, some DVFS/DPTC stuff has to be done more carefully. Trim out some stuff and group functions better as well. 2011-01-23 20:21:35 +00:00
system-target.h Better boost calculation for multifrequency CPUs. Frequencies between minimum and maximum count as fractional boost. 2011-01-22 18:30:24 +00:00
timer-gigabeat-s.c
usb-gigabeat-s.c Simplify and neaten-up usb.c a bit. USB_INSERTED and USB_EXTRACTED are always used as events to indicate cable state. USB_HOSTED is posted to indicated that a host was detected. 2011-12-15 00:14:36 +00:00
usb-target.h Gigabeat S: Make it a removable mass-storage device. Windows will assign a drive to only the main data partition by default. To access the bootloader partition instead, press 'Vol -' while it connects (in bootloader and firmware). Hopefully doesn't break anything for anyone. 2011-01-05 19:35:51 +00:00
wmcodec-gigabeat-s.c Gigabeat S/i.MX31/wm8978: Clean up clocking information in the general wmcodec/pcm drivers and move it to the target's wmcodec/i2s files. 2011-10-17 15:37:14 +00:00
